MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 722,916, dated March 17, 1903. Application filed May .16, 1902. Serial No. 107.572- (No model.)

efiicient driving mechanism of compact con-- struction whereby the carrying-wheels of the vehicle on the opposite sides thereof maybedriven, so as to compensate or differentiate for the variation in speed of the respective carrying-wheels when in turning the vehicle said wheels travel curves of different radii.

With this object in view myinvention comprises various novel features of construction and combinations of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a side elevation, partly in section, of a vehicle equipped with my invention. Fig. 2 is a bottom view thereof. Fig. 3 is a vertical section as on the line 3 3 of Fig. 1. Fig. 4 is avertical section as on the line 1 4.-of Fig. 3. Fig.5 is a vertical section as on the line 5 5 of Fig. 3.

1 designates the body of a vehicle, 2 the,

carrying-wheels therefor, and 3 the axles, the body being supported on the axles by springs 4 in the usual manner. The carrying-wheels 2 are mounted on the axles 3, as usual, so as to be rotatable at relatively different speeds in turning curves, 8m.

5 is a casing in which are arranged a series of motors, which may be of any suitable construction and driven by any suitable power.

In the present embodiment of my invention the casing contains four electric motors 6, the same being arranged around a {centrally-disposed sleeve 7, which is supported by the end heads 8 of the casing 5. The armatures 9 of the motors 6 are mounted on shafts 10, which are fitted to bearings 11 in the end heads 8, and the field-magnets 12 are supported between the sleeve 7 and easing 5 and are so arranged as to form a magnetic circuit common to all the armatures around the sleeve 7. Two of the shafts 10 extend outwardly beyond one end of the casing, and the other two shafts 10 extend outwardly be- 'yond the oppositeend of said casing, as shown. The outwardly-extendin g ends of these shafts are provided with pinions 13, which coact with spur-wheels14, affixed to the respective sections of a two-part shaft 15, extending through the sleeve 7. This shaft 15 is-parted, as at 16, about midway of its ends and is fitted to bearings 17 in the sleeve 7 and also to bearings 18, depending from the body of the vehicle. The respective ends of the shaft 15 extend outwardly and are provided with sprocket-wheels 19, which are connected by chains20 with sprocket-wheels 21, affixed to the hubs 22 of the two rear carrying-wheels ping to accommodate the other or in any way acting to waste the power.

I claim- 1. In a motor-vehicle, the combination with the carrying-wheelsfof an electric motor having a plurality of armatures arranged in a circle at right angles to the axes of rotation of said armatures, field-magnets forming a magnetic circuit common to the plurality of armatures, and gearing between said armatures and carrying-wheels.

2. In a motor-vehicle, the combination with the carrying-wheels, of a casing provided with end heads, a plurality of parallel shafts extending through said casing and j ournaled in said end heads, means for independently r0 tating said shafts, and gearing between said shafts and carrying-wheels.

3. In a motor-vehicle, thecombination with the carrying-wheels, of a casing provided with end heads, gear-wheels journaled in said end heads, a plurality of shafts extending through said casing and journaled in said end heads, means for independently rotating said shafts,

[O shaft, means for actuating said members,

gearing between said shaft and members, and gearing between said shaft and carryingwheels.

In testimony whereof I affiX my signature in presence of two witnesses.

GORDON J. SCOTT.
